It is *almost* academic with no parts availability on the 3126 HEUI pump (C7 pumps you can find tools and rebuild kits from China, etc - not so the 3126) - can't get parts AND cat wants the old pump REAL BAD or you lose your core so taking it apart isn't happening either. And who is gonna...

I don't believe they do spit. But no one seems to be be on the page I'm on so.... FWIW. Not one person I'm aware of has actually done a before/after of *just* beads and reported the results - not because no one has done that - because a bunch of people have done that and it basically does...

Yup. Exactly the same situation I've seen. The 3126 trucks just keep dong this. I'm sure you're going to turn in that pump for a core (don't blame ya) but I REALLY want to know what the hell is going wrong with them. The lack of understanding is killing me.

You NEED this kit anyway. For your roof rack weight, etc. This is the upgraded cylinder with cab floor reinforcing since the sheet metal where the ram attaches to the cab floor is like wet toilet paper. Mine was already bent and I had to porta-power it straight to get the reinforcing plates...

My man has a spare engine in his back pocket so I'm fairly confident he's using pics of that rather than his truck :LOL: ........ But that IS the (unseen) violence inherent in the system. But we can workshop the marketing a bit...... "The timing sensors are very well protected by the air...

This is just ALL pointing to that timing sensor code. The ECM has to "sync" to the timing sensors every time you restart the engine. If the signal isn't stable it will take a bit for the ECM to either see enough of the uninterrupted signal OR for it to give up and switch to a fallback strategy...

There is a primary and secondary timing sensor and it is likely that the ECM can run in a reduced state with just one of them. That is common in the EFI world. Fallback strategy..... Likely a wiring/connection issue I should think but sensors are also possible. That code is VERY SUSPECT for the...

Try 50-55 instead. You're junk is big and heavy. Congrats on your sizeable gear :sneaky: Tire pressure? I run the M1088 settings so 81 psi. Guessing at that weight the best it will get under ideal conditions is probably around 8 or just under. 7.8 to 8.2 would be believable for that combo if...

Engine speed no pattern..... well that's not one I have seen..... Code description and fault condition seem to suggest "intermittant or complete loss of signal from the primary speed/timing sensor for 2 seconds" I would be checking the timing sensors and their wiring on the drivers side rear...

Well that looks normal. Excellent. So how is the Ether bottle and the grid heater? You need the Atmo sensor for the 330 tune. But it's a silent code - won't show a check engine light. It is CAT #194-6722. It plugs into the harness - there's already a port and connector for it at the top of...

Get into CAT ET and run a HEUI pressure diagnostic. You can increase and decrease the pressure manually. You are looking at stability of actual pressure vs the target pressure. Should be +/- 5 psi or so. If it's jumping around a bunch it could indicate a problem and it needs to get the pressure...

Personally I have seen zero benefits to the IFS kit. I've installed two of them and I'm no longer interested in one for my own truck. In the three cases I've done 3126 HEUI pumps the injectors were totally fine and I never saw any metal on any of them. Injectors worked fine and continue to do...

I have mine setup for both. Either wet tank or glad hand using high flow 3/8" fittings and a universal female quick connect with integrated shut off that can adapt my truck to almost all other quick connects if I need to interface with someone else's trucks or tools.

Milton is a mixed bag. A lot of their cheaper stuff is basically slightly better rebranded Chinese crap. The military side of the equation is..... different. Totally different department with different mandates. I've sworn off buying their consumer/commercial stuff after some really pathetic...

This is the currently fielded inflation kit. *Parts* of this kit are included in the BII of the new trucks. This is the full shop kit but contains the quick-connect remote inflation system to get the soldiers away from the danger zone. Ya gotta ask for our recommendations on this stuff before...

Have the fuel lines been changed? If not that is the likely culprit. Sucking air into the system. Every one of these trucks has bad fuel lines. It wasn't a great choice of hose for that application. Definitely biodegradable though! Or..... the HEUI fairy cometh!

To find any BII left over from it's former life is a treat. That is a $300 bottle jack from US Jack. Service the seals and fluid and paint it. That, or another just like it, came with the truck when it was new along with some adjustable wrenches and lug wrench, tire inflator whip and glad hand...

Sounds like your grid heater isn't working..... Below about 18-20 it should engage the Ether if it has any and that will disable the grid heater so if the bottle is empty..... Ya kinda stuck if she won't kick over. Block heater and take a nap.

I tore a 3126 HEUI pump down.... Mind you I was legitimately a pump rebuild technician in one career path.... I could not find any smoking gun. I can say there is a surprisingly large amount of soft yellow metals in it and the whole thing is quite intricate and TINY inside. Pistons the size of...

Yep. Found some of the same in my truck. Also not uncommon to find lost equipment or tools. My truck came with a pair of channel lock branded pliers (definitely from an older GMTK so someone's field loss) and BAE left me a pneumatic riveter sealed up inside the cab wall...... Still looking for...
